Electromyography (EMG) is a diagnostic procedure that assesses the health of muscles and the nerve cells that control them by measuring the electrical activity produced by skeletal muscles. It is commonly used to diagnose conditions affecting muscle tissue or nerves, such as muscular dystrophy, carpal tunnel syndrome, and amyotrophic lateral sclerosis (ALS).

Electromyography

A diagnostic procedure is a systematic method used by healthcare professionals to identify a disease or condition in a patient. It involves gathering patient history, conducting physical examinations, and utilizing diagnostic tests to reach an accurate diagnosis and guide treatment decisions.

health of muscles

Nerve cells, or neurons, are the fundamental units of the brain and nervous system responsible for receiving sensory input, processing information, and transmitting signals to other neurons, muscles, or glands. They communicate through electrical impulses and chemical signals, enabling complex processes such as thought, emotion, and movement.

nerve cells

Electrical activity refers to the flow of electric charge, often observed in biological systems like the nervous system and heart, as well as in electronic devices. It is crucial for transmitting signals and powering devices, playing a foundational role in both biological functions and technological applications.

conditions affecting muscle tissue

Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration due to defects in muscle proteins. These disorders vary in severity and age of onset, and currently, there is no cure, but treatments focus on managing symptoms and improving quality of life.

muscular dystrophy

Carpal Tunnel Syndrome is a condition caused by compression of the median nerve as it travels through the carpal tunnel in the wrist, leading to symptoms like numbness, tingling, and weakness in the hand. It is commonly associated with repetitive hand movements and can be managed through ergonomic adjustments, splinting, or surgical intervention if necessary.

carpal tunnel syndrome

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to loss of muscle control and eventual paralysis. Despite extensive research, the exact cause remains unknown, and there is currently no cure, only treatments to alleviate symptoms and improve quality of life.
